Agenda for today's call

We have two significant events coming up at the beginning of March: The talk and demo for the AmericaView/USGS meeting in Washington(March 6-7; Terry and PR atteding) and the OSG All Hands meeting in San Diego (March 5-8; Paul, Dan, Bobby, and Kevin attending). We have items to discuss relating to each:

  • Successful demo for AmericaView/USGS - Some issues, both technical and operational) related to making this demo successful have come up. They include the following:
    • NullPointerException on download. Download seems to complete successfully, anyway. (May be fixed by Friday.)
    • Performance: 150Mb/sec upload (1G file, 10Meg Block size, 16 Threads) 70Mb/sec download (1G file, 10Meg Blocksize, 16 Threads) In practice, this translates to 1:30 minute download time using L-Store vs 2:00 minute download using conventional file transfer. Needs to be much faster for the demo! What can we do to improve performance?
    • Can-we/How-to specify depots using the L-Store API.
    • How much space can we consume for the USGS demo (March 6th). Where should we put data? (see question 3.)
    • -1 (indefinite)keep-alive flag doesn’t seem to work – causes allocation to fail. (May be fixed by Friday.)
    • Update on status of LoRSview integration with L-Store -- Is it looking plausible or shall we start working on plan B?
  • Preparation for the OSG meeting:
    • Interaction/cooperation between Ultralight and Phoebus -- What are the options and oppportunities?
    • Demo of L-Root?
    • L-Store and SRM? dCache?

Other Agenda Items

Application Groups

  • Geospatial
    • Status of the TexasView demo preparations for AmericaView meeting
    • LoC funding and Collaboration with NGDA
  • CryoElectron Microscopy: Anything new?
  • CMS Particle Physics
    • Ultralight collaboration?(Paul, Alan)
    • Status ROOT_L: integrating ROOT and LN technology? (Dan/Paul)
  • Astrophysics?

Deployment and Operations

  • The most recent deployment schedule for REDDnet and L-Store software.
    • Is there any update on this schedule? A timeline of what will be deployed where and when?
    • There are demos planned for the beginning of March (AV meeting in Washington at least, maybe OSG meeting in SD as well).
  • Discussion of alternative strategy for investment in REDDnet deployment - The general idea is to buy more, but perhaps less well provisioned nodes, and try to deploy them to more places where application groups will fully populate the rack with storage. (Terry)

Technology: Hardware, Software

  • Review of current L-Store release schedule(Alan)
  • Status of the work on Phoebus (Martin)
  • Nevoa's driver level client: Shows up as another storage device under "My Computer" and speaks both L-Store and WebDav (Hunter)

Organization and Funding Opportunities

  • Library of Congress funding
  • NSF PIRE (Feb. 28th)-- Paul: Any word?

Events, Education, Outreach

  • List of upcoming events this Spring that we know about or that we're planning for. More details about what's planned are on the "at work" page
    • CMS Week -- February 26 - March 2, 2007 at CERN. -- Is anyone we know going to this?
    • OSG Consortium Meeting --- March 5-8, 2007 at UCSD
      • Who will be going to this? Paul, Dan, Bobby?
      • The agenda for this seems pretty closed. Will there be an opportunity to do things.
    • AmericaView Annual Winter Meeting-- March 5&6, Downtown Washington DC and at USGS Headquarters.
      • PR and Terry are on the agenda
      • Side meeting with interested parties
      • May be a NDIIPP PIs meeting at the same time, so may be able to make connections between groups
    • Internet2 Spring Meeting, Apr23-25, Crystal City Marriott, Arlington, VA
      • We have submitted proposals for a regular track session and a side meeting.
      • Expectation is that we'll be accepted for both.

Action Items from December call

  • Terry will get the LN wiki up and going (http://www.logisticalnetworking.org)
  • Alan will share the rough spec he's going to develop for libxio before he implements
  • Micah will recover and put on line the old IBP spec or, if that can't be located, do what he can to replace it.

Some Notes on the call
